Transporting and cooling device for plasma lava

Abstract

The present invention continuously transports and cools down plasma lava with no gas explosion under an indirect cooling; comprises fewer rotating parts for transportation; prevents radioactive pollutants from escaping out under an air-locked environment; and, avoids motor of transport caravan operating under high temperature, where the present invention can be applied to a plasma melting process for radioactive material.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a transporting and cooling device; more particularly, relates to transporting a metal bucket to a lava-discharge cooling unit through a transport unit to carry lava, then transporting and cooling down the metal bucket in a cooling tunnel, and then hanging the metal bucket to a storage bucket in a hanging cabinet to be stored, where the present invention can be applied to a plasma melting process for radioactive material. DESCRIPTION OF THE RELATED ART [0002] Using plasma with 10000° C. (centigrade) to deal with waste is becoming a mature technology. Because the plasma torch is run under 1650° C. when dealing with the waste, it is required to find ways to discharge and cool down the plasma lava, and to operate a plasma furnace under a negative pressure to prevent off-gas from escaping into the factory building. [0003] As disclosed in Taiwan, “a cooling device for an incinerator with a dust-collecting by a high-pressure sp...

Benefits of technology

[0004] Therefore, the main purpose of the present invention is to provide a device for transporting lava and cooling lava continuously, stabilizing plasma lava, and not polluting environment.

[0005] To achieve the above purpose, the present invention is a transporting and cooling device for plasma lava, where a metal bucket is hanged to a conveyer by a hanger; the conveyer is driven by an electric motor to transport the metal bucket to a lava-discharge room; an elevating plate in the lava-discharge room lifts the metal bucket and positions it in a cooling jacket to joint with an opening of a plasma furnace for being loaded with plasma lava while the high-temperature plasma lava is cooled down by the cooling jacket; after finishing discharging the plasma lava and sealing the metal bucket with a cover, the metal bucket is remained still for at least 2 hours to be cooled down below 500° C.; the metal bucket is pushed to a carrying track of a cooling tunnel and the cooling tunnel comprises a cooling-water jacket, a cooling-air entrance, an air distribution pipe and a cooling-air exit; the metal bucket is transported seat by seat in a cooling tunnel with a transport caravan to its exit to be positioned and the temperature on the exterior surface of the metal bucket is cooled down to 60° C. during 20 hours by a water cooling system and an air cooling system; the metal bucket is hanged by a positioning hanging device out of the cooling tunnel to be processed with a surface radiation dosage detection, a weight measuring and a recording; and, the metal bucket is hanged to a hanging cabinet to be stored in a storage bucket of 55 gallons sealed with a cover. As a result, the present invention is an air-locked device preventing radioactive pollutants from escaping out; continuously transports and cools down plasma lava without the risk of gas explosion under an indirect cooling; comprises fewer rotating parts for transportation; and, avoids motor of transport caravan being operated under high temperature, where the present invention can be applied to a plasma melting process for radioactive material. Accordingly, a novel transporting and cooling device for plasma lava is obtained.

Problems solved by technology

In the above cooling device, water is directly in touch with the material to cool it down, so it is not suitable for cooling plasma lava of 1650° C.; especially the plasma lava will be cooled down into grains in lack of radioactive stabilization.

So, the prior art does not fulfill users' requests on actual use.
